Volume 6, page 500, note a:
He [Roger (de Clare), Earl of Hertford (d. 1173)] m. Maud, da. and h. of James DE ST. HILARY, by his wife Aveline.
K.S.B. Keats-Rohan, in Domesday Descendants, p. 690 (2002), states that Maud's fee is entered separately in her husband's return in the Cartæ Baronum of 1166.
[Adrian Channing, in April 2002, pointed out Maud's appearance in Domesday Descendants.]
